INSPECTION PROCEDURE HINT: In contrast to normal malfunction diagnosis for components, circuits and systems, DTC P1604 is used to determine If any other DTCs are output, perform troubleshooting for those DTCs first. . (a) Freeze frame data exists, but the malfunction (starting difficulty) has not reoccurred and the malfunction conditions are unknown. (1) The engine speed recorded in the freeze frame data is 0 rpm (the engine does not crank). HINT: If the battery voltage is less than 6 V during cranking, there is a high probability that engine friction is abnormal. If the battery voltage drops to 5 V or less when starting the engine, the battery may be malfunctioning. If the battery voltage fluctuates while cranking the engine, it can be concluded that cranking is being performed. When the engine speed is 0 rpm, the crankshaft position sensor and/or an ECM may be malfunctioning. 3UR-FBE ENGINE CONTROL SYSTEM: SFI SYSTEM: P1604; Start... |
